Froth flotation of Aljustrel sulphide complex ore

2017-5-26  The effects of mineral liberation and chemical reagents dosage were assessed for the froth flotation of a complex sulphide ore from the Aljustrel mine. The process showed increased susceptibility for variation of grinding time. Depression of unwanted minerals improved significantly for longer grinding times, however the copper recovery also decreased. Reduction in the particle size was required as a

FLOTATION OF COPPER SULFIDE ORES - STEPHAN

The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.5, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the flotation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.
